Abstract
The present invention relates to a backlight module and a preparation method therefor, and a display panel. According to the present invention, solid white ink is attached to a second base plate, and then the solid white ink corresponding to positions of bonding pad units is removed by means of laser engraving, so as to prevent the screen-printing white ink from damaging the second base plate. Aligned assembling is performed on a first assembly and a second assembly using a vacuum pairing device. The vacuum pairing device may be reused in other preparation processes of the display panel. Therefore, the device investment can be reduced, and the production costs can be lowered.
